Abstract: DOCUMENT SENSING MEANS          Abstract A document sensing apparatus includes a phototransistor (12) for generating a first or second voltage depending on whether or not, respectively, a document is present at a sensing location, and a capacitor (36) for providing a second voltage whose peak value is determined by said second value.  A voltage comparator (30, 38, 40) compares said first and second voltages and provides an output signal indicative of the presence of a document at the sensing location if said first voltage is less than a predetermined fraction of said second voltage.  A microprocessor (44) controls the operation of a circuit (74-1) which provides, as necessary, a charging current to said capacitor (36) so that, while a document is present at the sensing location, said second voltage is prevented from falling by a significant amount, thereby preventing problems occurring if a document remains at the sensing location for a prolonged period due to a feeding irregularity.

Title: Engine brake system for all types of diesel and gasoline engines
Inventor: ECHEVERRIA GREGORIO J
IPC: F02B1/04
Filed: 1991-10-25
Abstract: ABSTRACT     An engine brake system for use in all types of diesel and gasoline engines,  comprising a control means disposed,  in the main embodiment of the invention, on the top of the line of valve rocker arms,  seated on the supports of the rocker arms, and a dislodgement valve installed in the intake manifold of the engine,  the valve  remaining closed until the brake  system  is applied.   An actuating device acts when the brake  is applied, longitudinally displacing the control means,  whereby the rocker arms of the exhaust valves are uncoupled from the corresponding tappet rods thereby impeding the exhaust valves to open, whereby the  gases  trapped  in the cylinders  put  up resistance to the ascending movement of the pistons in their exhaust stroke.   The discharge  of  the  gases  toward  the  environment,   via  the dislodgement valve, occurs when the opening of the intake valves begins at the start of the intake stroke of the pistons.

Title: Invisible air bag cover door
Inventor: GARDNER JOHN A
IPC: B60R21/2165
Filed: 1991-11-27
Abstract: A vehicle steering wheel has a decorative panel concealing a storage compartment for an inflatable air bag.  The panel has a covering which comprises a backing plate having a U-shaped cut line framing the storage compartment and defining a cover door having a hinge line connecting the ends of the cut line U.  An inner layer of foam is interposed between the backing plate and an outer skin layer.          The skin has a peripheral groove outlining the door and comprises a hinge section overlying the hinge line and a weakened tear seam line overlying the cut line.  The groove is cut through at the bottom along the tear seam line but not along the hinge section.          Inflation of the air bag will force the door outwardly, fracturing the foam layer along the tear seam line to swing the door away from the opening about the hinge section to enable deployment of the air bag outwardly of the panel.  The cuts in the panel layers can be made before or after a molding process.  Alternate constructions creating the tear seam line are disclosed.

Title: A method of making a fiber preform of varying thickness for manufacturing a part made of composite material of the type having a ceramic or a carbon matrix
Inventor: OLRY PIERRE
IPC: B29C70/24
Filed: 1991-12-02
Abstract: In a portion of the preform to be made in which the preform is to be of reduced thickness by having a recess formed therein, a mask is interposed between pairs of adjacent layers, the mask being made of a thin film of material through which the needles can pass during needling while opposing the passage of significant quantities of fiber taken by the needles, and after it has been needled, each layer is cut out around a line corresponding to the outline of the recess in the preform at the level where the layer is situated in the preform.  A mask situated between two cutout layers occupies an area that is not less than the area between the cutout lines of the two layers, such that the portions of the layers that are delimited by the cutout lines are not securely connected to the remainder of the preform by the needling, thereby enabling the recess to be formed after all the layers have been needled by withdrawing the cutout portions of the layers and by peeling off the masks.

Abstract: A drink through container lid of the type formed from thin thermoplastic material and which is used as a closure cap on open mouthed beverage cups is disclosed.          Conventional lids of the foregoing description include one or more lines of weakness in the main body portion of the lid and which in part define the drink through segment of the lid.  Normal breakage of this segment is initiated by hand at a location on the bottom of the skirt, which may or may not also include a lift tab projecting outwardly from the  bottom  of  the skirt.    In  accordance  with  this invention, the lift tab is positioned above the bottom of the remainder of the skirt, and proximate to that portion of the outer wall of the groove of the lid which is in frictional engagement with the beverage cup to which it is attached.  By locating the lift tab close to the area of frictional engagement of the lid to the cup, less force is required  to  initiate  fracturing  of  the  thermoplastic material in this area, and reduces the likelihood of the entire lid becoming separated from the container to which it  is  attached when  only separation  of  the  removable segment  is  desired. Means  for  further promoting the fracturing of the material can also be located at opposite ends of the lift tab.
